Specification of Letters Patent.

Patented N ov. 3, 1914.

Application led January 20, 1914. Serial No. 813,225.

To all whom it may concern:

Be it known that IMNATHANIEL A. MAsER, a citizen of the United States,residing at Vineland, in the county of Cumberland and State of NewJersey, have invented new and useful Improvements in Sanitary DentalTrays, of which the following is a specification.

My invention relates to new and useful improvements in sanitary dentaltrays, and has for its object to produce a device of this character fromglass or other sanitary material which may be used for holding a numberof different medicines, and other objects of the dental profession whichwhen not in use will be sealed to prevent contamination anddeterioration or evaporation of the medicines, and to also temporarilyhold certain instruments to keep them in a practically sterilecondition.

Another object of the invention is to pro vide a single tray having anumber of compartments adapted to hold all the necessary articles fortreating a tooth which may be placed upon the ordinary bracket tableWithin easy reach of the doctor, thereby eliminating unnecessary stepsand the necessity of looking for medicines in the medicine cabinet.

A further object of the invention is to provide a device of thischaracter whereby the necessity of providing individual medi cinebottles is eliminated, and which eliminates the necessity of the doctorhandling individual medicine bottles, from which the odor of thedifferent medicines is often transferred to the doctors fingers, thelatter being over objectionable to both patient and doctor.

lVith these ends in view this invention consists in the details ofconstruction and combination of elements hereinafter set forth and thenspecifically designated by the claim. l

In order that those skilled in the art to which this inventionappertains may understand how to make and use the same, I will describeits construction in detail, referring by numeral to the accompanyingdrawing forming a part of this specification, in which- Figure l, is aperspective view of my improved sanitary dental tray. Fig. 2, is asection at the line 2 2 of Fig. ,1, looking in the direction of thearrow, one of the ground glass tops being removed from its well, and

tacle; and Fig. 3, is a section at the line 3-3 of Fig. l, looking inthe direction of the arrow, the waste receiver being removed.

In carrying out my invention as here embodied 2 represents the body ofmy improved sanitary dental tray formed from a single block of glass orother sanitary material of similar nature and supported in any suitablemanner, the supports as here shown comprising four integral glass feet3, one situated at each corner at the bottom.

In the body of the tray are formed a number of wells 4, the side wallsof which preferably converge toward the bottom and said side wallsadjacent their upper ends are made when the ground glass tops 5 areplaced therein, each of said tops being provided with a knob or handhold 6, whereby said ground glass tops may be readily and quicklyremoved or replaced. The body of the trayis also provided with tworeceptacles 7 and 8, the latter being provided with a channel 9 in whichrest the edges of the cover 10, said cover lying flush with the top faceof the body when in place. This cover is also made of glass and isprovided with a knob or finger hold l1, whereby the same may be liftedto remove or replace it. The receptacle S which is closed by the cover10 is adapted to receive and hold certain objects used in the dentalprofession, such as sanitary cotton pellets and by inclosing them inglass they are kept in a sanitary condition until they are ready foruse. The receptacle 7 is adapted to receive a carton or other wastereceiving device 12, so that waste, cotton or other objects may beplaced therein, and when said carton is full, the same may be removedand thrown away.

Adjacent one edge of the tray is formed a longitudinal cavity or recess14 in which are placed pliers and other instruments, when not in use,and because of the material from which the tray is made, saidinstruments are kept in a relatively sterile condition, because the trayis not likely to catch or retain dust or other foreign matter.

A tray of this character being made entirely of glass may be readilykept clean and in a sterile condition for it can be washed with hotwater or acids to cleanse the same.

Having thus fully described my invention, what I claim as new anduseful, is

In combination a glass body provided with the waste receiver removedfrom its recepground so that a perfect air tight closure is y aplurality of medicine wells, a cotton reamine@ my signature in thepresence of tvvo ceivng receptacle, zn, Waste recelverreceptasubscr1bing witnesses.
